One object of the invention is the provision of an atomizer of improvedcompact construction which particularly adapted to form a toiletteaccessory for dispensing a liquid per- Iume.

Another object of the invention is the pro vision of an improvedatomizer of the character described having a rubber bulb provided withnovel means for collapsing same to supply air for spraying;

A further object of the invention is the provision of a device of thecharacter described having an improved adjustable means for regulatingthe spraying effect of the device. v

A still further object of the invention is to provide a device of thecharacter described comprising few and simple parts, which shall formwhen assembled an ornamental toilette accessory, which shall be cheap tomanufacture, easy and simple to operate, and practical and efficient toa high degree in use.

Other objects of this invention will in part be obvious and in parthereinafter pointed out.

The invention accordingly consists in the features of construction,combinations of ele- This invention relates to spraying devices merits,and arrangement of parts which will be exemplified in the constructionhereinafter described. and of which the scope of application will beindicated in the following claims.

In the accompanying drawing, in which is shown one of the variouspossible illustrative embodiments of this invention,

Fig. 1 is a Vertical sectional view showing the internal construction ofa liquid perfume spraying device embodying the invention Fig. 2 is afront elevational view thereof; and

Figs. 3 and 4 are cross-sectional views taken on lines 3-3. and l.1 inFig. 1 showing,

respectively, the construction of a regulator member and nozzle support.

Referring in detail to the drawing, denotes a spraying device embodyingthe invention adapted to dispense liquid perfumes, medicines or thelike. Said device is seen to comprise a container or bottle 11 made ofsuitable material preferably porcelain or glass for holding a supply,ofliquid perfume-12to be sprayed from an atomizer 13 mounted to form aclosure for the top opening 11 of the bottle 11.

To secure said atomizer 13 in position, a connecting collar 14 isfixedly secured in any welllrnown manner, as by'cementing to a shoulderportion 11 on the rim of the bottle opening 11 Said collar is internallythread ed as at 14 to engage an external thread 13 of the atomizercasing 13 The collar is also formed with an upstanding ledge 14 adaptedto fit into a peripheral groove 13 in the atomizer casing 13 when thelatter is screwed into the collar 14 as shown in Fig. 1.

The atomizer casing 13 may be cylindrical in shape and has atransversely extending partition wall 13 formed with an outwardlyconcaved center portion which serves as a,

seat 13 for a rubber bulb 15. The seat 13 has a tubular portion 16axially extending downwardly therefrom into the bottle, and a nipple 17formed with aperipheral lip 17 is threaded into the seat 13 so thatlthelip projects into the concavity above the seat. The bulb has an opening15 to receive said lip, and the cooperation of the parts is such thatwhen the bulb engages with the lip of the nipple, the seat 13 conformsto the con tour of the bulb and forms a rigid support therefor. If nowthe bulb .is collapsed, air will be forced therefrom through the bore 16of the tube 16 into the bottle 11.

A regulator 18 is provided at the lower end of the tubular portion 16 tocontrol the flow of air into the bottle. Said regulator includes a cap19 having a wall portion 19 which may provided with suitable means forengaging the lower end of the tubular portion 16. A plurality of holes19 are bored through the wall portion 19 adj acent the end of thetubular portion 16 thus constituting adjustable means for throttlingsaid holes 19 in proportion as the regulator cap 19 is screwed up ordown on the end of the tubular portion. The bore 1.6 of the tube 16 isenlarged at its lower end as shown at 16 to provide a chamber from whichthe supply of air may flow through said holes 19 into the bottle 11.

The atomizer 13 also has a nozzle QOha-Ving an orifice member 2O whichmay be integrally constructed with the casing 13 Said member 20 hascommunication with the bottle above the level of the liquid so as tofreely receive air therefrom. For dispensing" the liquid from the bottlean outlet tube 20 is provided,.said tube having its lower or intake endsubmerged in the liquid 12 and its upper end or outlet 20 extending intothe member 2O incoaxial relation therewith, leaving an annularpassageway for the air. The outlet tube 2O may be'secured in position tothe easing 13 by soldering as at 21, and by a spider 22 within themember 20*. The member 20 may be threaded externally to engage a closurecap 23 which can be secured to the atomizer casing 13 by any suitablemeans such as by a chain 24. i

F or collapsing the bulb 15, a pressure lid 25 is provided toreciprocate in the casing 13 and forms therewith a chamber to enclosethe bulb. To permit the bulb to be readily collapsed, the pressure lidis constructed to have a central downwardly extending projection orfinger 25 -which concentrates the pressure exerted on the lid tocollapse the bulb easily. A spring 26 returns the pressure lid to itsnormal position, and a ring member 27 which is threaded to the casing 13releasably retains the lid in the casing, said ring member 27 extendingbeyond a shoulder portion 25 of the lid to serve as a stop for thelatter as will be clearfrom Fig. 1. An air valve 28 permits the bulb tofill with air in the usual manner.

The operation of the device 10 is now apparent. On depressing thepressure lid, the finger 25 contacting with the rubber bulb 15 collapsesthe latter against the seat 13 The air in the bulb is forced throughholes 19 in the cap 19 into the bottlell where pressure will be exertedon the surface of the liquid 12 and cause the same to rise and flow outof the tube 20*. Simultaneously, air will flow r through the member 20to render a fine atomization of the liquid being sprayed from the outletend of the tube20".

If a greater spraying effect is desired, the regulator cap 19 isadjusted to increase the size of the opening at the holes 19*, thusproviding for greater spraying of the liquid 12 and causing acorrespondingly increased flow of air through nozzle 20.

lVhen the device 10 is used as an accessory forming apart of a travelingoutfit the bottle may be filled with liquid and the regulator cap 19screwed up to completely close the holes 19 therein. If accidentalpressure should be exerted on the pressure lid, the contents of thebottle will not be placed under pressure by the air from the bulb and noliquid will be accidentally sprayed from the bottle. lVith the cap 23 inplace on the nozzle 20 and the regulator cap screwed tightlyin closedposition absolute safety against accidental spillage of the liquid fromthe bottle is assured.

A dominant feature of this invention resides in the means provided forsupplying the air pressure to dispense and atomize the liquid. It willbe noted from the foregoing description that in accordance with thisinvention no pump or other like mechanism visible to the user orextending from the device is employed. The pressure lid 25 is at alltimes substantially within the top casing 13 and never extends furtheroutward from the casing than shown in the drawlng, thus forming asubstantially flush closure for the casing and cooperating with themember 27 to make an ornamental cover for the container as a whole. Byreason of this construction, the device may be easily operated with onehand and presents to the user a neat, compact appearance such as isrequired to make it suitable for a ladys dressing table or boudoir.

It will thus be seen that there is provided a device in which theseveral objects of this invention are achieved, and which is welladapted to meet the conditions of practical use. 7

As various possible embodimei'its might be made of the above invention,and as various changes might be made in the embodiment above set forth,it is to be understood that all matter herein set forth or shown in theaccompanying drawing is to be interpreted as illustrative and not in alimiting sense.
